SPRING-MOTOR.

SPECIFICATION forming part of Letters Patent No. 279,827, dated June 19,1883.

Application filed May 4; 1881. Renewed April 17. 1883. (No model.)

To aZZ whom, it may concern:

Be it known that I, DAVID SHWE, a citizen of the United States, residingin the city and county of Philadelphia, State, of Pennsylvania, haveinvented a new and useful Improvement in Spring-Motors, whichimprovement is.

fully set forth in the following specification and accompanyingdrawings, in which-- Figure 1 is a side elevation of the motor embodyingmy invention.- Fig. 2 is a face view, partly broken away and sectional.Fig. 3 is a section in line a" m, Fig. '2, the arbors being uncut.

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention consists of a spring-motor having a winding-stem formedwith a socket, into which projects a tenon or journal on the end of thearbor of the springs and barrels, said socket being free toturn on saidtenon,

for the purpose of winding the spring attached to the first barrel.

It also consists of two or more sets of arbors,

barrels, and springs, in combination with connected barrels.

It also consists in making the barrels in skeleton form.

It also consists of a combination of arbors, springs, and barrels, saidsprings winding on the arbors, respectively, from their outer totheirinner ends and from their inner to their outer ends. a

Referring to the drawings, A represents a frame for supporting thevarious parts of the motor.

B represents a winding post, which is mounted on the frame A, andprovided with a ratchet-wheel, G, with which engages a pawl connected tothe frame.

On the inner end, of the post B is a socket, a,- into which projectsfreely a tenon or journal, I), on one end of an arbor, D, or vice versa,the other end of said arbor being mounted on the frame A.

Fitted loosely on the arbor D, side by side, are two barrels, E E,containing reversely-. coiled springs F F, one end of each of which A isconnected to its respective barrel bya spur,

c, thereon, and the other end to the arbor by a spur, d, 011 the same.The inner end of the winding-post B is screwed into or otherwise rel E,so that said barrel and post move as one.

G represents an arbor, which is mounted on the frame A and extendsparallel with the ar bor D. Fitted loosely on said arbor G, side byside, are two barrels, H H, containing reversely-coiled springs F F, oneend of each of which is connected to its respective barrel by a spur, c,thereon, and the other end to the arbor by a spur, d, on the same.

J represents a spur-wheel, which is attached to the barrel E, and mesheswith aspur-wh eel, K, attached to the barrel H. t L representsaspur-wheel, which is attached to the barrel H, and adapted tocommunicate the power of the springs or serve as the driving-wheel ofthe motor.

hen the stem B is properly rotated-in the present case to the right-thebarrel E winds the spring F from the outer end inwardly. As said springis connected to the arbor D, rotary motion is imparted to said arbor ina manner different from and independent of the motion of the barrel E,this being permitted by means of the free connection of the arbor withthe winding stem B, the said spring F being wound from the inner end andgiving motion to the barrel E, and consequently to the connected wheel Jthereof. Motion is thus imparted to the wheel K and the barrel H, andthe spring F'of the latter is wound from its outer end by said barrelupon the arbor G,

firmly secured to the adjacent head of the bar which, rotating, windsthe spring F from its inner end and imparts motion to the barrel H, andconsequently to the attached wheel L, which, as has been stated, is thedrivingwheel of the motor; but the number of arbors, barrels, andsprings may be increased as de: sired. Of course the rotation of shell Eby means of stem B will wind spring F considerably before the strain onsaid spring is transmitted to arbor D. The resistance of spring F willcounterbalance to some extent the action of said spring F on said arbor,and thus prevent it from turning too easily.

It will be seen that the several springs wind at the same time and allrun down at the same time; but the power of tension is that of onespring, while the duration-is as the number of I00 I cut them away orconstruct them in skeleton form, as shown.

Owing to the free or broken connection of the arbor D and winding-stem Bby means of the journal I) and socket a, as has been stated, I amenabled to wind two springs on the same arbor and have independentaction of the springs, whereby, if the winding were from the center, thesprings would act in conjunction. Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is t 1. Ina springunotor, the winding-stem and socket, in combination. with theshell E, turning with said socket, the arbor D, j ournaled in saidsocket, and the spring F, attached at one was?)
